Hello all,

I can't access website when i'm surfing from my server, all sites except microsoft give me a 403 error.

See print screen.

This wouldn't happen to be on Server 2003, would it?

Yes it is on Windows Server 2003 Entreprise Edition

I don't have a copy of 2k3 handy to list the steps for you, but IE on 2k3 has an extra security feature. Can't remember what it is called.

It always pops up automatically for me by default unless I change a setting.

Try creating a new user and then use that user to access the net...hopefully you'll get the security prompt and that will help you find the option to add sites or disable it.

Sorry for the cryptic advice

Nah... It's not the enhanced security doing it, that doesn't give you 403's. But there's just not enough infos for us to be able to guess either.

-Is it only IE doing that or do other web browsers work just fine?

-Did you check see if DNS queries resolve properly? (right IP address), or even if you can access other sites directly by IP instead of name (w/o getting 403)?

-If you're still getting 403's, try using a http debugging proxy (or LiveHTTPHeaders in Firefox) to capture the requests so we can see what's hapenning (paste captured infos in code tags or such)

-Does everything else network related work just fine? (and if IP addr & subnet is OK)

-Any valuable informations on the actual 403 page? i.e. NOT the "friendly" 403 from IE but the "real" one. (is it from squid? local IIS/apache? anything at all?)

-Any firewall filtering queries or restricting sites in use?

...

Give us some more infos and then we can try making an educated guess, but with so little infos, there's no way to tell.

My current wild guess would be, somehow your IEAK build of IE is messed up (I'd have censored the branding if I was you... "nice" script in /pv/ )

Good call. You can't get a 403 back unless the server was actually contacted.

Could also be a local content-filtering proxy sending bad outbound packets/headers.
